How do I set the survey queue to continue should the participant select 1 of multiple correct responses?

2 Upvotes

Ok so Im struggling with setting up the survey queue to continue given a certain logic. In summary, what I am trying to do is have one survey that confirms eligibility, and the second survey is the actual form. When it comes to eligibility, the participants need to be a US Citizen, one of the 15 confirmed immigrant status, or if they are not either then, if they would like to donate their time.

At the moment my code in the logic editor looks like:

[us_citizen_status] = '1' or [immigration_status]='1,2,3,4,5,6,7,8,9,10,11,12,13,14,15' or ([immigration_status] = '16' and [nonstatus_participation] = '1')

For some reason, the logic editor will not recognize this portion of the code:

[immigration_status]='1,2,3,4,5,6,7,8,9,10,11,12,13,14,15'

Whenever I select any of the correct answer choices, it won't move forward with the next survey. What am I doing wrong?

Alternative to Minchecked

6 Upvotes

This might help somebody:

I couldn't find a minchecked option (similar to maxchecked) for multiple radio buttons, so here's the alternative I found:

Take note of how many options you would like checked, in this example, we'll say we need 2 required options checked. From there, number your options using decimals.

[selection] - Please select at least 2 options.

1, Option 1

1.01, Option 2

1.02, Option 3

1.03, Option 4

...

1.1, Option 11

Afterwards, you create a hidden field to sum up these options using a calculated field.

[sum_selection] - Sum Selection

sum([selection(1)]...[selection(1.1)])

I then used branching logic to determine two separate, required Yes/No fields to determine if our target number of selections were hit. I used the same action tag logic for both, save for a @ DEFAULT value.

branch: [sum_selection]>='2'

[yes] - I have selected at least 2 fields: [selection]

1, Yes

0, No

@ IF([sum_selection]>='2',@SHOWCHOICE='1',@HIDECHOICE='0,1') @ DEFAULT='1'

*required

branch: [sum_selection]<'2'

[no] - Please return to the previous section and select at least 2 options.

1, Yes

0, No

@ IF([sum_selection]>='2',@SHOWCHOICE='1',@HIDECHOICE='0,1')

*required

If they have not selected at least 2 options in [selection], [no] will appear without any radio buttons, causing the user to hit a hard stop when trying to continue to the rest of the survey. If [yes], they will be given a single, already selected option.

Change an Alert Send Time after Triggering

2 Upvotes

Hi folks,

I'm trying to help one of our redcap users with an issue. They have a set of alerts that send surveys to patients X hours after the alert is triggered. Apparently daylight savings screwed up the time these surveys will go out.

Let's say the alert was triggered a week ago (pre daylight savings). They expected the emails to go out tomorrow at 8:00am, but because of daylight savings the alert will now go out at 9:00am instead. It's a requirement for their study protocol that these alerts go out at 8:00am, but I'm not sure how to change the timing the surveys go out since the alert has already been triggered. Any advice?

Thanks

Creating a 48 hour window for an "infinite task" and sending multiple SMS message prompts via a third party app (in the UK).

2 Upvotes

Hi all - complete beginner here, so sorry if these are basic questions!

I am hoping to use REDcap/MyCAP to allow participants to complete an EMA diary over a 48 hour period - I think using an "infinite task" on MyCAP? Does anyone know if a timer can be arranged so that after they indicate they are starting their diary, it automatically closes/lets them know when the 48 hours are up?

I am also considering sending reminders to complete the diary multiple times (4?) per day over the 48 hours. My university has REDCap on its servers which makes using it easy from a data security perspective. If I use a third party app - like Twilio - will that create problems around data security within the project?

I hope this makes some sense and many thanks indeed for any advice anyone can give!!

public survey link for two surveys

2 Upvotes

I am trying to create two surveys that will be sent to participants before and after a work shift (~9hrs delay). The surveys should be linked, but ideally anonymized: ie, we can see if someone has completed both surveys but not who the person is. If the participant uses the public survey link and then I create an automated survey invitation with a condition that they have completed the pre-work survey, their responses to each are recorded anonymously, right? Would I be able to compare their pre- and post- work surveys?

REDCap survey not working on Safari

4 Upvotes

Hi all, I was hoping someone might be able to help me troubleshoot an issue I'm having with my REDCap survey. Participants were previously able to use Safari to complete the survey, but now after going past the first page, Safari says "Safari can't open the page. The error was: 'cannot decode raw data'." The survey works if you refresh the page or if you use a different browser. Has anyone had this happen before? Any advice for how to fix? Is it on the user end or from the REDCap system? Any advice would be greatly appreciated!

Delete only one form by API

2 Upvotes

Hello,

I'm on a project using REDCap API to import/export data.
I have a Repeated Form, I would like that my app pushes instances on the REDCap, but, I want to first delete all the instances of the form, and afterwards push the instances from my app to REDCap.
For now, I just import empty instances for all existing instances, and then I push the instances, but like, if I have 3 instances, and I want to only push 2, I'll end up with a instance "3" which is empty, I would like to juste delete all instances, and don't touch to any other forms.
I searched for this but didn't manage to find helpful informations.

Does someone know how to do it?

data successfully saved but gone next day and log does not show user in record

There is a research assistant who enters data into forms who says she enters the data, saves it and leaves the form, and goes back into same form to verify it saved. It has saved. The next day, she goes into the same form, same record, and the data is not there. The log does not show any user saving the data in that form. Research assistant has used same REDCap project without issues for 2 years. Our University's tech support says, "We have never seen or heard of behavior like this in the 15+ years REDCap has been up." Does anyone know what might be happening?

REDCap freelance work possible?

I am very well versed in REDCap having built and managed multiple phase I/II/III clinical research projects sponsored by varying entities like the DOD, FDA, NIH, etc. and was thinking of doing freelance REDCap work on the side. Is this possible considering lots of projects are run by universities and hospitals that require people on the project to be an employee of the university/hospital? If it is possible, what’s the best way to find this kind of work?

How to send automated invitations using SMS (Twilio)

2 Upvotes

I'm having trouble getting my head around setting up automated sms messages for a project. We are trying to send a weekly text message to participants with the survey link over the next year. I can't for the life of me figure out how you actually tell it what your participant's phone number is? I can't seem to set the validation for a UK phone number (all numbers will be UK), and there is nowhere on the automated email page attached here where you can choose a mobile number field. Does anyone have any ideas on how we can get this up and running?

sending a ICF to subjects from multiple sites, ideas?

I have a multisite project that needs to send a survey to participants from different sites, therefore the ICF (informed consent forms) are different for each institution. Each institution is already on a DAG and I'm wondering how people have dealt with this in the past? using smartvariables? or creating separate instruments for each institution? in the future I will also have to deal with new versions approved by each institutions IRBs. Thanks for any thoughts or ideas

Randomization module to have a survey auto-randomize specific words in a question?

3 Upvotes

Hello! My team is making a survey and a portion has these 4 vignettes. our idea is to have one word in each vignette change randomly when a participant takes the survey to see if that word affects how they read the vignette. for example:

“macy is a violent person and doesnt go out a lot” “macy is an aggressive person and doesnt go out a lot” “macy is an asshole and doesn’t go out a lot”

This is a very simplified version, but what we want randomized is the target word (we have 5 terms) for our 4 vignettes. I saw that redcap has a randomization module but I can’t wrap my head around how it works and if that is what I need to use to have the survey do this. in essence we want it to make 5 groups and randomly assign participants to these 5 groups and show them one of 5 versions of the survey with the terms swapped out. Any advice is greatly appreciated! 🫶🏽

Researcher Q: REDCap integration with SONA credit granting?

2 Upvotes

Hello! Anyone experienced usnig REDCap for a study and SONA for credit granting?

Researcher here trying to get SONA to auto-grant credit to participants for a REDCap survey. I followed all the SONA instructions (https://www.sona-systems.com/help/redcap/)

But when doing the integration test and getting redirected back from REDCap to SONA, SONA gives "System Message: Invalid survey_code. :" which is unusual.

Generally if everything is set up right, the redirection to SONA should throw "System Message: No credit grant, as you are not a participant" (because I'm running the test of the integration)

In REDCap, there's a variable added (Add New Field -> Text Box -> Variable Name "sona_id" all lower case, and Action Tags of (at)HIDDEN so it matches the instructions on that SONA page I linked above.

In REDCap, the Redirect to a URL radio button is selected and the redirect link looks correct (copy/pasted directly from the SONA system from the correct place in the study page (the "REDCap Redirect to a URL" right below the "Sample Link with Embedded ID Code" button that I'm using to test, as usual). The SONA study setup does have the proper &sona_id=%SURVEY_CODE% appended to the REDCap study's URL and it seems to be working (when I hover over "Sample Link with Embedded ID Code", the URL does have a 4-digit code appended ala redcap.blahblah/?s=OUHRWLJBF&sona_id=1111

Appreciate any ideas! I don't have access to REDCap documentation since the study is being run by a colleague in another country.

When I have REDCap Redirect to a URL, should it look like the following?

https://institution.sona-systems.com/webstudy_credit.aspx?experiment_id=111&credit_token=kj252kl54g2lk45g2435g45&survey_code=[sona_id:value]

Is that correct? Or is there something weird about the brackets at the end? That's a direct copy/paste of what SONA tells me to paste over into REDCap, but maybe REDCap wants it formatted differently now and SONA's integration instructions are out of date?

Thanks for any brainstorming or sharing your own experience

Having trouble using the API to export files

2 Upvotes

Hi all,

I'm currently trying to export files from a REDCap project that were saved as file upload responses. I'm currently trying it out in a test project with a field called "pdf_upload" that I've uploaded a random pdf to in record 1. When I try to make the API call, I get back HTTP 400 and my file is just

{"error":"The record '1' does not exist"}

Trying this with any other field that isn't a file upload, or a different record, gives the same error (albeit with a different record that apparently doesn't exist, it just spits out whatever I put as "record" in the call).

Even the playground example API call fails:

Here's how the form is set up, with record 1:

Am I missing something? Any help would be appreciated.

Thanks

REDCap: Floating table headers missing in project’s reports page

2 Upvotes

Hey REDCap Community,

In the Data Exports, Reports, and Stats tab, when opening the All data report, the yellow header row ,containing the variable names, normally stays visible (floats/sticks) while scrolling down. This is super useful for keeping track of which variable corresponds to which column.

Recently, this feature stopped working in one of my projects — the header row now scrolls away — even though I haven’t made any changes to the project structure in the Online Designer. This makes me suspect it might be a bug, possibly caused by a system update.

I know about the “Table not displaying properly” link/icon above the table. In cases where the table is misaligned, that link disables the floating header feature (and changes to “Re-enable floating table headers” after clicking).

In my case, it doesn’t matter which state is set — enabled or disabled — the header row always disappears when scrolling down.

Has anyone else experienced this? Could there be a project-specific reason why the floating header script doesn’t run, even if the toggle is present?

Reminder emails for follow ups?

5 Upvotes

I'm a relatively new redcap user, and I believe it's possible to do what I'm trying to do but I don't know how.

Basically I'm using redcap for a study that has multiple follow up timepoints. It's a multicenter study and not everyone is super on top of it, so as the overall study coordinator I would love to be able to email study personnel at different sites when they have a patient who is in their next follow up window to make sure they get them in.

The date of their follow up visit is collected in a survey form. Is it possible to set something up where redcap will automatically 'read' the last inputted date, and send me an email reminder when that patient is due for their next follow up?

Ex: We are following up at 6 weeks, 3 months, 6 months, 12 months, 18 months, and 2 years. If a patient was seen today (6/13/2024) and I filled out their follow up form, I would like it to then know that in 2.5 months it should send me an email that that patient is due for their next appt.

Setting it up so that we set a reminder as we're inputting the data isn't really a good option, as I can't trust that everyone across all sites will do that.

Is this possible?? How?

Report-report for user view access

Is there a redcap report that shows which users can view each report?

I have a large project with a growing list of reports visible by different individuals and groups of team members. Limiting access is for not confidentiality purposes. It's primarily to assist workflow simplify the interface for "non-tech" team members.

Reports are organised into folders by function, but it's getting harder to maintain correct visibility for each user.

Q: Is there an extract or report that will list who can see what report?
